The single biggest issue holding back FFXIV needs to be specifically addressed.

[DNO]

Yoshida has done a remarkable job turning this game around. Each and every patch things get better, yet one issue consistently remains with no end in sight. We've all experienced it, knowingly or not, because it has an influence on every single aspect of the game.

-Have you ever been running throughout town, and seen a character(or enemy) in front of you jump into the ceiling or through walls?
-Have you ever attempted to heal somebody running next to you, only to be told they're out of range?
-Have you ever seen an enemy go Red with nobody in sight, only to see a party member run up 5 seconds later and attack with a melee strike?
-Have you ever done DH and seen one of the Eyes charge up their stationary AoE far away from you, then proceed to watch it 'glide' along the floor while charging until its right on top of you?
-Or, perhaps, experienced something like this?

An extremely simple video that I think adequately shows the very root of the problem. While the video itself may seem 'trivial', rest assured the cause behind it is the same as in all the above examples.

I am, of course, talking about the horrid Server/Client relationship in Eorzea. These things happen to a very small extent in any online game, but to nowhere near the extremity of in FFXIV. All frustrating occurrences to say the least, and I think I'm being pretty kind phrasing it that way.

I've given nearly a year of leeway waiting for this to be fixed. It's crippling to all facets of gameplay, and quite frankly it's pretty darn embarrassing. All the content in the world won't make the game enjoyable if this has to be tolerated, and I shudder to think of the amplified effects it will have when we're moving at Chocobo speeds.

Every patch we hear about the 'server upgrades/optimizations', when are you going to get to the one that truly matters?

dude do that with ff11.. it does the same thing and i bet you the server/client is fine in that game to everyone. i dunno what SE issue is with LS commands but they gotta hurry up i mean its not even in 1.19 or 1.20.... thats mab we get it sometime in the new year.....

Go make a video in XI, it's not the same.

Quoting this just to give it a nod of approval.
I've tested myself after seeing the video in the OP of this thread (and reading the comments on that video) just to see, since someone there did ask.
It quite literally is not the same thing at all in FFXI.
